BOLD - ID
  Cytochrome Oxidae Subunit 1 [COX1]   Intergenic Spacer Region [ITS]  


The BOLD Identification System (IDS) accepts sequences from the 5' region of the mitochondrial gene COI and  returns a species-level identification when one is
possible. Further validation with independent genetic markers will be desirable in some forensic applications.

The reference database of validated records is used by default and is recommended for all identification purposes.


Search Databases:
All Barcode Records on BOLD (427,853 sequences)
Every COI barcode record on BOLD with a minimum sequence length of 500bp (warning: unvalidated database and includes records without species level identification). This includes many species represented by only one or two specimens as well as all species with interim taxonomy. This searchonly returns a list of the nearest matches and does not provide a probability of placement to a taxon.
Species Level Barcode Records (380,725 sequences/37,849 Species)
Every COI barcode record with a species level identification and a minimum sequence length of 500bp (warning: unvalidated dataset). This includes many species represented by only one or two specimens as well as all species with interim taxonomy.
Reference Barcode Database (135,480 Sequences/13,774 Species)
Validated subset of the full database with a minimum sequence length of 500bp and containing only those species represented by three or more individuals showing less than 2% sequence divergence
